Why Should A Potometer be Allowed to stand before starting the Experiment​

It is crucial to avoid air bubbles in the assembled potometer. The plant stem must be cut under water to prevent airlocks forming in the xylem. All fittings must be tight so that the only way the apparatus can lose water is by the plant transpiring.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
